The idea behind the word of the day is to give you a word. Then use it in a sentence to illustrate its usage. Check this out:

Word of the day for Dec. 2:

Example sentence:

Word of the day for November 30:

I just find it a little amusing that the example sentence uses a different word than the one it is supposed to be teaching. Anyway, it is still a nice website.

That is funny. Thanks for pointing it out!
